The Study Of Ecology To Wild David's Deer And Community Co-management In Hubei Shishou

Since the ease outside the national-level nature reserve of David's deer of Shishou Hubei of 33 David's deer of 1998, 8 among them run away to Yangbotan, have 25 besides crossed the Changjiang River, run away to the Machuan village of south bank of Changjiang River, have become the real wild population. In order to clarify the population situation of the wild David's deer's population and the development trend, implement wild population and habitat to monitor, promote David's deer's population to reply smoothly strongly and melt wildly, since February of 2004, until April of 2005, on average in each on the month, I go on observing, contrasting and visiting at the Machuan village of the south bank of Changjiang River, Sanheyuan, Yangbotan of the north bank of Changjiang River and the nature reserve. At last, obtaining the comparatively full and accurate data, I draw the following conclusion after analysing.Under the wild state putting out, David's deer's population's annual average rate of increase expands more than 30%. Wild David's deer population logic growth curve takes the form of" J ", its growth model is Nt =33e0. 247t.The instantaneous rate of increase of the population is up to 0.247.Tthe wild David's deer's population will increase at quicker speed before it is up to 5.773 years old expecting.Under the natural environment, the ecological variety of the behavior of wild David's deer is more abundant than the population in the nature reserve, and it demonstrates the behavior space that the population fails to express in the nature reserves. For example, wild David's deer individual is more stalwart, it advance 3-5 days before the population in the nature reserve in in heat and mating, and the behavior of controlling the group is more abundant and so on. That is the ecological countermeasure when the wild population faces the pressure.The wild David's deer requires the habitat differently in different seasons. The wild David's deer spends most time having a rest in the daytime, ingests to concentrate on in early morning and at dusk. The meadow is the eating place mainly of a wild David's deer. No matter in oestrous, the woods are all liking the habitat for the most of wild David's deer's.Wild David's deer population has 146 now, but the plant in the habitat can support 1000 heads about wild David's deer eating. The fodder of the wild David's deer's population still takes fresh grasses as the core in autumn and winter.However, wild David's deer's population increases quickly, the life and production of residents around has been influenced by a certain degree, even conflicted. So, carry on...
